What is the effect of anaerobic respiration (strength training)?

Increase in diameter increase in glycolysis

What is smooth muscle innervated by?

The ANS and not the NS

Does smooth muscle have striations?

NO

Where can you find smooth muscles?

GI Tract, Uterus, airways, ducts

15

Describe the nucleus of smooth muscle?

Mononucleate

16

How are filaments arranged in smooth muscle?

Diagonally across the cell

17

Describe the cross bridge cycle in smooth muscle

Increase in calcium ionsCalcium binds to calmodulinCalmodulin binds to Myosin Light Chain KinaseKinase phosphorylates the cross bridges activating them - bind to actin and cause contraction, ATP used to release the myosin from the actin

There is no blocking tropomyosin in smooth muscle

18

What causes the relaxation of the smooth muscle?

Myosin light chain phosphatase

19

What's the result of dephosphorylating the cross head when the myosin is still bound to the myosin?

Inhibits the cross bridge cycle, decreases the rate of ATP splitting, maintenance of tension with low ATP consumption, useful in blood vessel walls that need to stay open for long periods of time.
